The so-called \(\mathrm {SLE}_\kappa (\underline{\rho })\)  processes [1]} are a natural generalization of \(\mathrm {SLE}_\kappa \)  processes where one keeps track of several marked points. More precisely, consider \(\underline{z} = (z_1,\dots ,z_n)\)  where \(z_j \in \overline{\mathbf {H}}\)  and let \(\underline{\rho } = (\rho _1,\dots ,\rho _n)\)  where \(\rho _j \in \mathbf {R}\) . Then the \(\mathrm {SLE}_\kappa (\underline{\rho })\)  process with force points \(\underline{z}\)  and weights \(\underline{\rho }\)  arises from the family of conformal maps in the same way as ordinary \(\mathrm {SLE}_\kappa \)  by solving (REF ) with \(W_t\)  given by the solution to the SDE
\(dW_t &= \sqrt{\kappa }dB_t + \sum _{j=1}^n \mathrm {Re}\!\left( \frac{\rho _j}{W_t - V_t^j} \right)dt,\quad dV_t^j = \frac{2}{V_t^j - W_t} dt, \quad V_0^j = z_j.\)
